Yes, an isosceles triangle has two equal sides and two equal base angles.
four sides and a base
If the base is a polygon with n sides, the pyramid will have n+1 faces. Triangle base (3 sides) gives 5 faces, Quadrilateral base (4 sides) has 5 faces, etc.
An isosceles triangle has 2 equal sides and 2 equal base angles
An isosceles triangle has two equal sides and two equal base angles.
Two sides of an isosceles triangle are equal. The base is the other side.
